Low-voltage differential transmission is based on low volt-AGC differential signaling, high-speed signal transmission from a circuit board system to fast data transmission between different circuit systems can be achieved using low-voltage differential transmission technology, and its application is becoming more and more important. Low-voltage differential signals have a high noise suppression function relative to single-end transmission, and their low voltage swing allows differential lines to

With the rapid development of related technology and China's communication market, the main network of the mainstream SDH equipment rate has risen to 10G, and 2.5G SDH transmission equipment by these more high-end equipment extrusion, network application level began to move down, gradually into the edge layer, replacing the original in the edge of the 622M equipment. On the other hand, with the rapid growth of the bandwidth demand of data and Internet service, more and more requirements are put

Recently used an LVDS interface camera, 640*480 grayscale image, data rate of 600Mbps, bit width 10bit,ddr double edge sampling.The implementation of data acquisition needs to use the SerDes module in the FPGA, has now been simulated, and then after the success of the board to write a concrete implementation of ideas, and logical structure.Mainly includes the function, iserdes of the bilateral along the sampling realization, the iserdes bit synchroniz

I. Overview 1. The display drive architecture of flisikar imx6: 2. Objectives: Because the sabrelite Development Board itself has provided LVDS interface, the target screen is LG's LP101WX1-SLN2, its main parameters are: Resolution: 1280*800 Color: 18 digits Color: 262 K Clock frequency: 69.3 M Hz 2. porting process 1. First, connect the screen interface to the LVDS interface of the sabrelite Developmen

The recent project needs to use differential signal transmission, so we look at the use of differential signals on the FPGA. In Xilinx FPGAs, differential signals are sent and received primarily via primitives: Obufds (differential output buf), Ibufds (differential input buf).Note that when assigning pins, only the pins of the signal_p are assigned, and the Signal_n is automatically connected to the respective differential pair pins, without the LVDS

VGA VGA(Video graphics Array) Is a computer display standard proposed by IBM in 1987 using analog signals, which is outdated in today's PC market. Even so, VGA is a low standard supported by the most manufacturers, and personal computers must support VGA before loading their own unique drivers. For example, the boot sc

MINI-VGA is a video interface that is used to replace standard VGA on laptops and other systems. In addition to its tight composition and output VGA video signal, the MINI-VGA port also adds the ability to output AV terminal signals and s-video signals by expanding the display identification data (Extended display iden
